I have a Kenmore Ergo3 that I LOVE! I also does embroidery which is one of the main reasons I bought it....oh yea, plus I got it for a FANTASTIC price. I do most of my sewing on that. I also have another Kenmore that's probably about 25 years old. Was to go to my oldest, but she showed no interest in sewing unless it was ME doing it. So, I have that one that I use once in a while. I also have my grandmothers Singer (heavy duty, she made ships sails with it). That just sits and holds fabric on top. Love the cabinet it is in. I also have my moms Singer Touch N Sew. That needs a cleaning and overhaul. Don't think it's been used in 20+ years. I also have a New Home that was given to me that needs a part to the bobbin area. Will have that fixed once we get back to the states.
I favorite foot to use is my 1/4 inch. Just love it! But....I need to get another one since it's starting to not hold the 1/4 inch. I drop it alot. lol
